Replace the "simple-bus" simplification by the proper bus for
IXP4xx memory or device expansion.
Use chip-select addressing with two address cells on all the
flashes mounted on the IXP4xx devices. This includes all flash
chips.
Change the unit-name from @50000000 to @c4000000 as the DTS
validation screams. The registers for controlling the bus are
at c4000000 but the actual memory windows and ranges are at
50000000. Well it is just syntax, we can live with it.

The PCI hosts had bad IRQ semantics, these are all active low.
Use the proper define and fix all in-tree users.

This adds the beeper GPIO to the NSLU2 completing the board
support.

The IXP4xx expansion bus is 24 bits (256 MB) that is memory
mapped between 0x50000000-0x5fffffff usin a set of chip
selects. The size of the windows is 16 or 32MB defined by
the boot loader system configuration at runtime.
Create a rudimentary simple-bus and move the flash memories
to the expansion bus, inside the SoC.

This adds a basic PCI host definition to the base device
tree for IXP4xx and then further details it in the 42x
and 43x device tree include, also the specific target
devices NSLU2 and GW2358 get proper PCI swizzling
defined.

This adds ethernet to the IXP4xx device trees.

This adds a device tree for the IXP4xx-based Linksys
NSLU2 and Gateworks GW2358 which encompass the Gateworks
Cambria family.
These will be the first IXP4xx device tree platforms.
